Use Fast Dimensioning to Add Dimension Constraints
General
- You can use Fast Dimensioning to add distance, angle, diameter or radius constraints.
- Fast dimensioning adds a diameter constraint to a circle and a radius constraint to an arc.
- Note that Fast Dimensioning always adds an angle constraint between divergent lines, while the distance constraint turns divergent lines parallel.
Add a dimension constraint
- Select Sketch | Fast Dimensioning.
- Select the element being dimensioned, such as a line, circle or a pair of points.
- Click the position of the dimension.
- The program opens the dialog box Edit Constraint.
- Edit the data in the Edit constraint dialog box.
- Select OK.
- If the dimension constraint is the first distance, diameter or radius dimension of the sketch, then the dimension scales all the lines of the sketch to match the entered dimension.
- Repeat steps 2 to 5 to add new constraints
- Stop adding constraints
- Select another function or
- press the V key or
- press the Esc key or
- click the middle mouse button.
Note:
- You can dimension the diameter of a part which is rotationally symmetric.
- The dimension will change between distance and diameter when you move the cursor over the rotation axis before positioning the dimension.
- The type of one of the lines must be Rot.Axis.
- This works for both the Distance and the Dimension constraints.
- After positioning the dimension you can drag the it elsewhere and it will remain a diameter dimension.
